SHIPPING-CASE.

Specification of Letters Patent. Patentgd Mar. 29, 1921 vApplication filed January 26, 1920. Serial No. 354,173.

ers or cases constructed of fiber board, corrul gated board or equivalent materials. It has for its object a'l shipping case provided with a closure which effects marked economy in material and at the same time affords a case4 that has the maximum capacity of its dimensions and has amaximum strength. These features will better be understood when the detailied description has been given.

The fiber shipping cases that have been ast have beenthose which are provided with flaps that are extended from the tops`and bottoms of the side walls in the blank and which, when' the side walls are united, can be overlapped. These `overlapping flaps' were first sealed by gluing them together. A later. development was to use a sealing strip of aper that was pasted over the overlapping aps. And sometimes both gluing and a sealing strip have been used. A still further improvement is that `described in Patent #1,174,943, of which patent I amone of the atentees. This consists in utilizing a bla e-like anvil between the overlapped flaps in the closing end and wire-stitching or riveting the flaps together. l'Ihis method of sealing the overlapping flaps has been very useful, but it has become recognized that' the overlapping flaps require the use of considerable material that might be..

saved. An econom in material has been effected by using a. anged cover that can be inverted and inserted within the top open ing. This permits an anvil to be placed on the inside 'of the cover flanges and the same riveted or wire-stitched to the to s of the side walls. This construction ('ea led the solid end box is, however,.open to the objection that the maximum capacity of the dimensions ofthe box cannot be utilized for packlng. It also provides a pocket to hold water, snow, or catch other material. The projecting edges also very often break in handling and interfere with the stacking of the boxes one upon another. It is the object of the present invention to afford a container which effects the economy of material of a case sealed in this way but at the same time 1s stronger, utilizes the full capacity of the box for lpacking, and does away with the objectiona le pocket.

. The side walls of the case are formed by a single blank which is scored or creased at a:

to be folded in four places to form the four corners of a rectangular case. These side walls are designated a. At one end of the blank is a iap b adapted to fold inside of the adjoining side wall and be fastened thereto b wire stitches c or other fastening means. his completes a rectangular inclosure and the four side walls.

Y A flanged cover d made from a blank such as shown in Fi 7 may be fitted over the bottom ofthe sie walls as shown in Figs. l and 4. It may be fastened thereto bv wireV stitches or other fastening means e. No dificulty in elenching these fasteners will be met with as any horizontal arm anvil can be used to vclench the fasteners. p Y

This method of fastening the cover to the top or the closing end of the boi; obviously cannot be employed because no anvil can be gotten in the box to clench the fasteners. It is for this reason that the method. of inverting the cover and setting it in the .boX'

has been employed. I overcome the objec tions to this form of sealing thecase by providing each of the side walls of the case at the-closing end or top with a fiap f which is creased so it can be turned over as shown in Fig. 1. The flanged cover g is made large enough to fit over both the side wallsy'and the turned-back flap f. 5A blade-like anvil such as described in my prior- Patent #1,174,943 may then be inserted between the flaps and the side walls and wire stitches,

staples or other fastening means may be driven through the overlapped flanges Vand flaps and clenched on the anvil. This affords a shipping case that has a marked economy in the use of material, is stronger than one employing a cover inverted inside of the case. and provides no pockets. Furthermore, this caseis stronger than one having the overlapping flanges and covers up all crevices so as not to allow dust, Water or other material to enter.

yIt is preferable to stitch the flanges of the cover together as shown in Fig. 8 before the cover is placed over the case end but obviously it would be possible to do the stitching at the same time as the flanges are stitched tothe flaps. The Wings y which are turned in to fasten the cover flanges together also afford4 a reinforcement at the corners of the finished case.

In Figs. 9 and 10 a stitch z is taken to hold the flap to the side Wall before the cover I is stitched to the flap. This makes the cover cling to the side Wall better than in the form shown in the other views. What I claim is:

1. A shipping "case constructed of liber board or equivalent materia-l, having in ecmbination, a body portion having four side Walls and having relatively shallow flaps folded back upon and fastened each at one .point to the adjoining side Wall of the case before the same is sealed, acover having a relatively shallow flange fitted over the end of thebody of the case and over the shallow turned-back flaps, and fasteners driven into the overlapped flanges and flaps and clenched on the under side of the flaps between the flaps and the side Walls.

r2. A shipping case body constructed of fiber board or equivalent material from a single blank forming side walls united side by side in the blank with iaps on a plurality of the side Wall ends and a liap on the side of one of the side Walls at the end of the blank by which the side Walls are united to form the body of the case, in combination with a flanged cover fitting over the end of the body having flaps, the said flaps being relatively short and folded back and lying directly adjoining the side walls of the body under the cover flaps to which they are united to seal the case.

3. The combination of a shipping case body which is formed'simply of a blank having shallow iaps on'one side and a Hap at one end, said blank being scored to form the sides which are united by uniting the ends of the blank through the flap at the end of the blank, the other flaps' at the side of the blank being folded back directly adjoining the side Walls of the body, a flanged cover fitted over the end of the body With the said aps turned back, and metal fasteners driven into the cover fianges and clenched on the under side of the turnedback flaps'.

In testimony whereof I affix my signature.
